Multifocal basal cell carcinoma arising within a linear epidermal nevus

Abstract

Epidermal nevi are usually benign lesions with a lifelong course if left untreated. In rare cases development of basal cell carcinoma in such nevi has been documented. We describe a 32-year-old man with a multifocal malignant transformation within a congenital epidermal nevus.
